Herpevac Neonatal Substudy
Stopped early
Conditions studied: Herpes Simplex
In brief
The purpose of this study to look at the antibodies (proteins from the body's infection fighting system) in the blood of babies delivered by women who are participants in the Herpevac Trial for Women, and who were vaccinated with either two or three doses of (GlaxoSmithKline) GSK candidate vaccine gD2t/alum-MPL or hepatitis A vaccine. The goal of this study is to compare the herpes or hepatitis A antibody levels of the newborns to those of their mothers, and to see how much of the antibodies are still present in the baby at two and six months after birth. Approximately 2 teaspoons (10 ml) of the mother's blood will be collected at the time of delivery or within 15 days before or after delivery. Approximately 2 teaspoons of blood will be collected from the child's umbilical cord at the time of delivery, or 1 teaspoon (3-5 ml) of the child's blood will be drawn within 15 days after birth. Optional blood draws from babies may occur 2 and 6 months after birth.
